What F15 actually means
The machine isn't getting enough hot water in through its hot fill hose, so it has stopped the cycle.
Some Miele machines are plumbed to both a cold and a hot supply. F15 is raised specifically against the hot inlet ot not enough has arrived in the time the control allows, so the programme halts rather than carry on with a part-filled drum. The cold side can be perfectly fine, which is why the machine may have filled normally in the past or on other programmes.
What usually causes it
- Hot water stopcock or tap behind the machine turned off, or only part open
- Hot fill hose kinked or trapped behind the machine after it's been pulled out
- Blocked filter in the hose union at the hot inlet
- No hot water in the house at all \,, or the boker not running
- Faulty hot water inlet valve on the machine
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Check the hot tap serving the machine is fully open
- Run a hot tap in the kitchen to confirm the house has hot water
- Pull the machine forward gently and look for a kinked or squashed hot fill hose
- Turn the machine off at the wall for a minute, then power up and restart the programme
When to call someone
This sometimes clears with the checks above. If it comes back, it needs looking at properly. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
